:Patented Aug. 29, 1905.

Continuation of application Serial No. 200,973, filed March 31, 1904.This application filed January 13, 1905. Serial No. 240.901.

To all whom t may concern,.-

Beit known that I, WILLIAM NIEBUR, Jr., a citizen of the United States,and a resident of the city of New York, borough of Manhattan, in the'county of New York and State of New York, have invented a new andImproved Apparatus for CuttingPlastic Material, of which the followingis a full, clear, and exact description.

The invention relates to a device for cutting plastic material intoblocks or cakes.

Itis especially intended for cutting small cakes of butter from a largemass, and by means of my invention cakes of any size may be rapidly cutwithout handling the cakes in any way. This is a decided `advantage overthe devices heretofore commonly employed for the purpose, since when thesmall cakes are formed handling of the cakes may tend seriously tomisshape the cakes of butter.

The present application is a continuation of my copending applicationfiled March 31, 1904, Serial No. 200,973.

Reference is to be had to the accompanying drawings, which illustrate,as an example,the preferred embodiment of the invention, in whichdrawings like characters of reference indicate like parts in the severalviews, and in which Figure 1 is a perspective view showing the inventionin use. Fig. 2 is a detail section illustrating the operating-arm andratchet. Fig. 3 is a vertical section of the device, and Fig. 4 is abottom plan view.

The apparatus comprises a receptacle 10, which is preferably of metaland rectangular in form, as shown. This receptacle may be supported inany desired manner, either vertically or horizontally. As here shown, itis provided with four lugs 11,-having vertical pins 12 at their ends,these lugs being adapted to engage suitable holders 14, attached to avertical wall. lf desired, however, the device may be clampedhorizontally onto atable or other equivalent support. The ends of thereceptacle are turned over to form flanges 15, and these flanges areformed with notches therein, as shown. Both ends of the receptacle areflanged and notched to enable the device to be turned end for end, asdesired; but only one set of the flanges is used at a time. Thesenotched flanges 15 are intended to properly hold and space the wires 16,which extend across the discharge end of the receptacle 10 and vcrosseach other to form squares, said Wires serving to out the butter intosquare sticks, which are in turn cut into parts to form the cakes, whichwill be hereinafter described. It is clear that by adjusting the wires16 and increasing or diminishing their number the size of the-cakes maybe varied at will. vThe wires 16 are held and their tension readilyregulated by means of bars 17, having hooks 13 at their lower ends.hooks are adapted to be engaged by balls 19, of lead or other equivalentmaterial,formed on or fastened to the ends of the wires 16. Said barsare mounted in guidellanges 20 and 21. As here shown, there are three ofthese flanges, two numbered 20 and the middle one 21. Three are providedto enable the bars to be shifted so as to hold the wires at one end orthe other of the receptacle 10. Only two of the flanges, however, areactive at one time. The fianges 20 are formed with square orifices andthe bars 17 are squared to slidably lit therein. The upper ends of thebars, as best shown in Fig. 3, are formed with reduced portions 22,which fitvin round orifices in the flange 21. Said reduced portions 22are threaded and nuts 23 operate thereon. These nuts bea'r against theflange 21, and by means of the nuts the bars 17 may be moved to tightenor relax the wires 16. Said bars may also be shifted from the positionshown in Fig. 1 to a position in which, they engage the upper flange 20and the flange 21, thus permitting the wires to be placed on the upperend of the receptacle 10.

Projecting from the receptacle 10 is a suitable bracket 24, formed witha sleeve 25 at its outer edge, this sleeve running parallel with thereceptacle 10. Extending through said sleeve is a screw 26, to the upperend of which an arm 27 is removably or permanently connected in anydesired way. Said arm projects over the receptacle 10 and is connectedWith thev stem 28 ofa plunger 29. This plunger moves into the receptacleand is adapted to press down on the butter or other plastic material,extruding it from the lower end and between the wires 16. Coacting withthe Alower end of the screw is a nut 29, having a flange 30, adapted tobe engaged by a screw 31 at each end of the sleeve 25. Two brackets andscrews 31 and 32 are provided to enable the screw 26 and nut 29 to beshifted from one end to the other of the sleeve. The screws 31 serve tohold the nut 29 to turn at the ends of the sleeve. Arranged to swing onthe nut 29 is a forked block 33, between the limbs of which are arrangedratchet-teeth These IIO 34, formed` on the nut. Coacting with theratchet-teeth is a pawl 35, attached to the block 33. Said block isprovided with a socket 36, in which an varm 37 is loosely fitted. Saidarm has a pin 38 arranged to move in an arc-shaped slot 39 in saidsocket-piece 36.l This allows the rod 37 a limited turning movement inthe socket, the purpose ofwhich will be hereinafter fully set forth.Said rod 37 also carries a pin 40, projecting therefrom and having awire41 attached to it. Said wire is also attached,by means of anadjusting-screw 42, to an arm 43, attached to the free end of the rod37. The arm 43 serves not only as a holder 'for theA adjacent end of therod'37, but

alsoas la handle to facilitate the operation of theldevice.' Itwill beobserved that by swinging the rod 37 around the axis of the screw 26astep-byLstep turning movement willA be imparted to the nut 29, and thisnut will draw down the screw 26, bringing with it the parts 27, 28,and29, and thereby forcing the butter out from the receptacle. Simultaneouswith this swinging movement of the rod 37 and-itheforcing out of thebutter the wire 41 is intended kto sweep under the lowerl end of thereceptacle past the wires 16, cutting oil thebutter in small cakes. Vhenthe bar'37 is swung in one direction, the arm 43 and said rod`37 shouldbeturned in the socket-piece 36, so as' lto properly engage the wire 41with the wires 16, and when the rod 37 and its at'- tached parts arereturned the handle 43 should be rocked back so as to disengage the wirefrom the v receptacle. Therefore when the rod`37 moves in one directionit cuts the butterfinto cakes, and when it moves in the other directionit forces the butter out through the at one end' thereof for dividingthe plastic'v material intosticks', a follower operating in thereceptacle, a screw having connection with the follower, a nut engagedwith the screw and with a relativelystationary part, an arm attached:tothe nut, and a cutting-wire carried bythe arm and adapted to movepastthe discharge endof the receptacle.
